Miniature rose plant named `Ruififty`

ABSTRACT

A new variety of miniature rose characterized by a continuous and profuse production of very large Poppy Red blooms carried on very long, strong stems; the blooms are approximately 11/4 inches in diameter; its formed flowers having large petals which tend to marginally turn under and form points; and its free branching and vigorous growth habit produces a dwarf, compact, busy, free blooming plant suitable for use as a pot plant as well as for a garden decoration.

BACKGROUND OF THE NEW PLANT

My new variety of rose plant is the result of breeding efforts carried on by me at Hazerswoude, Holland, with the object of producing miniature rose plants suitable for production of flowering pot plants as well as to be useful for garden decoration. This plant originated as a seedling derived by my crossing of an unnamed seedling with the variety `Ruimin` (unpatented). The form and beauty of the flowers of this new plant and its very fine growth habit led me to propagate this plant, by cuttings, through several successive generations, which showed that the novel characteristics of this plant would hold true from generation to generation. Commercial propagation of this plant, by budding, is now being carried on in Holland.

DESCRIPTION OF THE DRAWING

My new variety of rose plant is illustrated by the accompanying photographic drawing, showing the vegetative growth and flowers of this variety and as depicted, the color is as true as is reasonably possible to make the same in a color illustration of this character. The specimens illustrated were grown with three plants in one pot in a greenhouse at Hazerswoude, Holland.

DESCRIPTION OF THE NEW PLANT

The following combination of advantageous characteristics is observed in the new variety:

(a) Readily propagated and grown on its own roots by cuttings;

(b) Exhibits a well balanced, compact and vigorous growth habit which is extremely floriferous;

(c) Blooms carried in clusters as well as one per stem;

(d) Exhibits an excellent aptitude for greenhouse forcing as a flowering pot plant and also as a very good comportment when used as an outdoor garden plant;

(e) Bloom color in general is Poppy Red.

The following is a detailed description of my new rose plant, the observations being made from plants grown in a greenhouse in Hazerswoude, Holland, in early December.

Throughout this specification color designations are based upon The R.H.S. Colour Chart published by The Royal Horticultural Society of London, England.
